Journal of the Iowa Academy of Science: JIAS

Because their flowers can be cross- and/or self-pollinated Verbena stricta, V hastata and V urticifolia are facultatively xenogamous. We suggest the flowers can be cross-pollinated because I) the fruit set of caged plants was substantially lower than that of open-pollinated plants, i.e. pollinators were necessary for typical fruit set and 2) the flowers of each species attracted a diverse array of hymenopteran, dipteran and lepidopteran pollinators that were capable of moving pollen between plants. Self-pollination was low due to the spatial separation of anthers and stigmas and/or an angled corolla that decreased the likelihood of pollen dropping from the anthers …

Atmospheric Response To 1988 Drought Conditions And Future Climate Implications, Michael D. Mccorcle

Journal of the Iowa Academy of Science: JIAS

Plentiful precipitation in the central United States is one of the basic components of the successful agricultural industry in the Corn Belt. A combination of moisture, wind, and topographic factors creates an ideal condition for rainfall over most of the region during the late spring and early summer. In 1988, many ingredients necessary for wet weather were absent. The region experienced a drought unequalled since the 1930's. The drought of 1988 demonstrated chat the symptom of drought, namely, dry soils, can exacerbate and even perpetuate drought conditions by decreasing available moisture, altering circulation patterns vital to storm development, and increasing …

Impact Of Global Warming And Cooling On Midwestern Agriculture, Louis M. Thompson

Journal of the Iowa Academy of Science: JIAS

The global warming since 1980 has been greater than it was during the warming trend from 1880 to 1940. This has caused concern that the very warm years of 1987 and 1988 might have been associated with greenhouse warming. However, the cooling trend from 1940 to 1980 occurred during a rapid buildup in greenhouse gases in the atmosphere. Although there may have been some greenhouse warming since 1880, the unusual warmth of 1987 and 1988 may have been caused by changes in the temperature of the equatorial Pacific Ocean, and changes in transparency of the atmosphere or ocher phenomena acting …

Population Estimates And Geographic Distribution Of The Yellow Mud Turtle (Kinosternon Flavescens) In Iowa, James L. Christiansen, Benny J. Gallaway, John W. Bickham

Journal of the Iowa Academy of Science: JIAS

The yellow mud turtle (Kinosternon flavescens) is an endangered species in Iowa known from six localities in the stare. The only large population is located on a private preserve on Big Sand Mound in Muscatine and Louisa Countries and is estimated to consist of 2,000 to 3,000 individuals. Following the removal of predators in 1979, density estimates have tripled as estimated by the Sequential Bayes Algorithm of mark-recapture data. Assuming the Big Sand Mound population was nor severely damaged by the drought of 1988, it is judged sufficiently large to serve as a source to enrich certain of Iowa's other …

Engineering Proteinase Inihibitor Genes For Plant Defense Against Predators, Clarence A. Ryan, Thomas Moloshok, Gregory Pearce, Gynhueng An, Robert W. Thornburg, Gerald Hall, Russell Johnson, Edward E. Farmer, Curtis Palm

Journal of the Iowa Academy of Science: JIAS

Small proteinaceous inhibitors (Mr<20,000) of the digestive serine proteinases of animals and microorganisms are found as moderately abundant proteins in storage organs and leaves of many plant genera. The proteins are powerful inhibitors of the digestive enzymes of plant predators and therefore are considered to be part of the array of defensive chemicals of plants. Proteinase inhibitor genes show excellent promise, using DNA technology, to manipulate plant genomes to express these biologically active proteins in order to improve natural defense systems. Members of two unrelated families of serine proteinase inhibitors found in tomato and potato plants, called Inhibitor I (monomer Mr 8000) and Inhibitor II (monomer Mr 12,300), are under both environmental and developmental regulation in different tissues of the plants. Genes coding for wound-inducible Inhibitors I and II have been isolated from both tomato and potato genomes and characterized. Tobacco plants have been transformed with the chimeric genes containing wound-inducible promoters fused with the reporter gene, chloramphenicol acetyl transferase, to assess promoter function and signal transmission. Transacting factors that regulate their expression in response to wounding are also being identified and purified. Intact genes are being employed to transform agriculturally important crop plants to determine their potential usefulness to enhance defensive capabilities of plants against herbivores and pathogens.

G90-1006 Setting Up A Family Council, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

A family sitting down together and talking about important thoughts, situations, and issues is certainly not a new idea--it has been practiced for centuries. It is an idea, however, that needs to be put to work in the present day.

1. Do you treat your child better, worse or about the same as you treat your best friend?

2. Does your child have equal status as a person with the adults in your family?

3. Do you assign chores and times to do them, or does your child help in the planning?

4. Do you try to make decisions about …

G90-985 Discipline -- An Effective Life Guide, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

There is no doubt that discipline is needed in families. Society could not exist if people acted without concern for others. Why, then, is there so much disagreement about this subject?

Parents often misunderstand and confuse the terms discipline and punishment. They see them as being the same thing but they are not. The dictionary defines discipline as "a system of rules governing conduct." It is "training that corrects, molds, or perfects." In contrast, punishment is defined as "retributive suffering, pain, loss, or penalty." The term discipline has its origin in the word "disciple" -- a follower who learns from …

G90-962 Introducing Solid Foods To Babies, Darlene Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains when and how to add solid foods to your baby's diet.

Good nutrition is the cornerstone of a baby's growth and development. The American Academy of Pediatrics strongly recommends breast-feeding for most full-term infants. No formula can replace the immunological protection a baby receives from colostrum -- the breast milk produced the first few days after birth. It's important to breast-feed for at least the first few weeks, even if it can't be continued for a long time. If breast-feeding is not your choice, or if it is discontinued before the baby's first birthday, commercially prepared infant …

University of Nebraska-Lincoln Extension: Historical Materials

Canning can be a safe and economical way to preserve quality food at home. Home preserved foods can provide a variety of nutritious food for your family all year long.

How Canning Preserves Foods

The high water content of most fresh foods makes them very perishable. Foods spoil or lose their quality for several reasons:

growth of undesirable microorganisms - bacteria,molds, and yeasts

activity of food enzymes

reactions with oxygen

moisture loss

In addition, eastern redcedar (a conifer) is found throughout the eastern hardwood forests. Conifer forests primarily contain ponderosa pine and Rocky Mountain juniper. The boreal forests contain a mixture of several of the above species and paper …

G90-990 Explosion Venting And Suppression Of Bucket Elevator Legs, David Jones

University of Nebraska-Lincoln Extension: Historical Materials

Explosion vents and explosion suppression devices limit the danger and damage associated with grain dust explosions. This NebGuide discusses these devices and design guidelines for application on bucket elevator legs.

The bucket elevator leg has been identified as a major source of grain dust explosions. As a bucket elevator leg conveys grain, the elements necessary for a grain dust explosion are possible. Fuel (grain dust in suspension above the minimum explosive concentration), oxygen and confinement are inherent inside a functioning bucket elevator leg. Introduction of an ignition source will initiate a grain dust explosion.

G90-1005 Fruit Tree Cultivars For Nebraska (Revised September 1997), William A. Gustafson

University of Nebraska-Lincoln Extension: Historical Materials

Proper fruit cultivar (variety) selection is important for successful and satisfying results from the home gardener's efforts. Selection should be based on family preferences, available space and intended use of the fruits. Harvest can be spread over several weeks if cultivars with different periods of maturity are planted.

It is important that homeowners select the kinds of fruit plants or cultivars that are best adapted for cultivation in their area of the state. They must have adequate hardiness to survive the winter, heat and drought tolerance to thrive in the summer, and the ability to survive spring frosts.

Cc90-352 Team Building: Developing A Productive Team, Arnold J. Bateman

University of Nebraska-Lincoln Extension: Historical Materials

Team building is an effort in which a team studies its own process of working together and acts to create a climate that encourages and values the contributions of team members. Their energies are directed toward problem solving, task effectiveness, and maximizing the use of all members' resources to achieve the team's purpose. Sound team building recognizes that it is not possible to fully separate one's performance from those of others.
